So that review says multiple times, that Debian is the OS of choice. I remember reading that a Remix-version of Fedora is the "official" RaspberryPI-Distribution.
Maybe that's the reason for some negative test results?
I think the article is accurate, and the recommended distribution is currently Debian-based. Here’s the official Raspberry Pi downloads page: http://www.raspberrypi.org/downloads
“Fedora 14 Remix
A little buggy, so for now we’re recommending beginners use Debian Squeeze.”
Maybe that's the reason for some negative test results?
